In experiments with dogs was shown the role of motivational and emotional structures of the hypothalamus in reproduction of the adaptive motor reaction both in classical and instrumental conditioned reflexes (alimentary and defensive). Change of parameters of electrostimulation gave a possibility to activate differentially the motivational, emotional negative, and emotional positive structures of the hypothalamus. Electrostimulation of the motivational structures reproduced alimentary but not defensive adaptive motor reaction and decreased the threshold of the motor reaction which was used as a signal during classical alimentary conditioning. Electrostimulation of the emotional negative structures reproduced defensive adaptive reaction and inhibited alimentary unconditioned response. Elaboration of the avoidance of the stimulation of the lateral hypothalamus was a proof for the activation of the emotional negative structures. Electrostimulation of the emotional positive structures which was used as an unconditioned stimulus during self-stimulation conditioning reproduced neither defensive nor alimentary conditioned response.
在对狗进行的实验中,显示了下丘脑的动机和情感结构在经典和工具性条件反射(食物性和防御性)中适应性运动反应再现中的作用。电刺激参数的改变使得有机会差异性地激活下丘脑的动机、负性情感和正性情感结构。对动机结构的电刺激再现了食物性而非防御性适应性运动反应,并降低了在经典食物性条件反射中用作信号的运动反应阈值。对负性情感结构的电刺激再现了防御性适应性反应并抑制了食物性无条件反应。精心设计避免刺激下丘脑外侧是激活负性情感结构的证据。在自我刺激条件反射中用作无条件刺激的对正性情感结构的电刺激既未再现防御性也未再现食物性条件反应。
